uxtheme: fix some issues in UXTHEME_LoadImage

[Frank Richter]

dlls/uxtheme/draw.c
  UXTHEME_LoadImage(): Set default image count to 1 to avoid division by
    zero in case image count property is not given.
  UXTHEME_LoadImage(): Properly support 0 state IDs. (Previously it was
    assumed that the state ID would be at least 1.)
